    Note: Mining safety mark (Safety mark number 630A: KAD230061; 1250A: KAD230061)

    Mining general-purpose mark (Certificate number: KA2022W1281-1/2)

    Product Functions

    ◆Power Management: Facilitates the reception, distribution, and control of electrical power in three-phase AC systems.

    ◆Motor Control: Enables the safe starting and protection of large high-voltage motors.

    ◆System Protection & Monitoring: Provides essential control, protection, and monitoring functions for substations and distribution networks.

    ◆Safety Interlocking: Incorporates multiple mechanical interlocks to prevent misoperation, including load break prevention, grounding switch/breaker interlock, and live compartment access prevention.

    Applicable Environment

    This switchgear is engineered for demanding industrial settings under the following conditions:

    ◇Ambient Temperature: Ranging from -25°C to +40°C.

    ◇Altitude: Standard units up to 2000m; special high-altitude versions available for up to 5000m.

    ◇Humidity: Maximum relative humidity of 95% at 25°C.

    ◇Surroundings: Installation sites must be free from excessive vibration, impact, and corrosive gases that could damage insulation or metal components.

    Product Highlights

    ◆Enhanced Safety & Convenience: Unique design allows grounding switch operation and handcart movement to test position without opening doors, maintaining cabinet ingress protection (up to IP54) and operator safety.

    ◆Robust & Reliable Construction: Enclosure and partitions are made from anti-corrosion aluminum-zinc coated steel, formed with multi-fold processes for high strength, precision, and durability.

    ◆High-Capacity Performance: Rated current is significantly increased to 1250A, with a breaking capacity up to 31.5kA, meeting the needs of modern, high-load mining and industrial applications.

    ◆Flexible & Modular Design: Features a compact, modular structure with independent pressure relief channels for each compartment. Standard and customizable widths and interchangeable handcarts (breaker, PT, metering) offer excellent configuration flexibility.

    ◆Advanced Operation: Utilizes a screw mechanism for smooth handcart movement and can be upgraded for intelligent, remote-controlled operation from a central dispatch room.
